Fall from grace, once saved always saved; both phrases say the same
thing. This basic idea is that we are saved when we do something. The something
is determined by which denominational church you happen to ask. Then from that
point on, you are saved and you cannot fall out of the state of being saved. The
reason you cannot fall is because of God's Grace. If you think it takes works
beyond this point of being saved, than it would be by your works and not by
God's grace that saves you. The following is a verse that backs the general
theory:

Romans 11:6 And
if by grace, then is it no more of works: otherwise grace is no more grace. But
if it be of works, then is it no more grace: otherwise work is no more work.

According to
this verse they might be onto something. Where their thinking falls short is
that grace comes through faith.

Romans 3:27Where is boasting then? It is excluded. By what law? of works? Nay: but
by the law of faith.28Therefore we
conclude that a man is justified by faith without the deeds of the law.

Romans 9:32Wherefore? Because they sought it not by faith, but as it were by the
works of the law. For they stumbled at that stumbling stone;

Galatians 2:16
Knowing that a man is not justified by the works of the law, but by the faith of
Jesus Christ, even we have believed in Jesus Christ, that we might be justified
by the faith of Christ, and not by the works of the law: for by the works of the
law shall no flesh be justified.

Ephesians 2:8
For by grace are ye saved through faith; and that not of yourselves: it is the
gift of God: 9 Not of works, lest any man should boast. 10 For we are his
workmanship, created in Christ Jesus unto good works, which God hath before
ordained that we should walk in them.

So if we're
saved by grace because of our faith, then work is still not necessary, right, WRONG. Here's where
our works are needed. By works we show our faith. If we're not doing good works,
our faith is mere hear say.

James 2:14What doth it profit, my brethren, though a man say he hath faith, and
have not works? can faith save him?

James 2:17Even so faith, if it hath not works, is dead, being alone.

James 2:18Yea, a man may say, Thou hast faith, and I have works: show
me thy faith without thy works, and I will show
thee my faith by my works.

James 2:20But wilt thou know, O vain man, that faith without works is dead?

James 2:21Was not Abraham our father justified by works, when he had offered Isaac
his son upon the altar?

James 2:22Seest thou how faith wrought with his works, and by works was faith made
perfect?

James 2:24Ye see then how that by works a man is justified, and not by faith only.

James 2:25Likewise also was not Rahab the harlot justified by works, when she had
received the messengers, and had sent them out another way?

James 2:26For as the
body without the spirit is dead, so faith without works is dead also

The
misconception is if you believe your works are what saves you, than your wrong,
but works are still necessary. You can not save yourself. You do good works
because it is a commandment and it shows you have faith. To not do "good
works" is a sin. Works will not save you, but no works or bad works, will
condemn you.

Matthew 16:27For the Son of man shall come in the glory of his Father with his angels;
and then he shall reward every man according to his works.

1 Corinthians
3:13Every manís work shall be
made manifest: for the day shall declare it, because it shall be revealed by
fire; and the fire shall try every manís work of what sort it is.

1 Corinthians
3:14If any manís work abide
which he hath built thereupon, he shall receive a reward.

1 Corinthians
15:58Therefore, my beloved
brethren, be ye steadfast, unmovable,
always abounding in the work of the Lord, forasmuch as ye know that your labor is not in vain in the Lord.

2
Corinthians11:13For such are false
apostles, deceitful workers, transforming themselves into the apostles of
Christ. 14And no marvel; for Satan
himself is transformed into an angel of light. 15Therefore it is no great thing if his ministers also be
transformed as the ministers of righteousness; whose end shall be according to
their works

1 Thessalonians
4:11And that ye study to be quiet,
and to do your own business, and to work with your own hands, as we commanded
you;

2 Timothy 4:5But watch thou in all things, endure afflictions, do the work of an
evangelist, make full proof of thy ministry.

Titus 1:16They profess that they know God; but in works they deny him, being
abominable, and disobedient, and unto every good work reprobate.

James 1:25But whoso looketh into the perfect law of liberty, and continueth
therein, he being not a forgetful hearer, but a doer of the work, this man shall
be blessed in his deed.

Revelation
22:12And, behold, I come quickly;
and my reward is with me, to give every man according as his work shall be.

So let's put this together. We are saved by God's grace,
grace is freely given to those who have faith and our works show faith.
So what happens if we stop our works? I think the answer to that is we
would fall from grace. But there are no scriptures to back this theory are there?

Matthew 13:22 He also that received seed among the
thorns is he that heareth the word; and the care of this world, and the
deceitfulness of riches, choke the word, and he becomes unfruitful.

1Corinthians
10:12 Wherefore let him that thinketh he standeth take heed lest he fall.

1 Tim. 4:1 Now
the Spirit speaketh expressly, that in the latter times some shall depart from
the faith, giving heed to seducing spirits, and doctrines of devils; 2 Speaking
lies in hypocrisy; having their conscience seared with a hot iron;

Heb. 2: 1
Therefore we ought to give the more earnest heed to the things which we have
heard, lest at any time we should let them slip.

Heb. 3: 12 Take
heed, brethren, lest there be in any of you an evil heart of unbelief, in
departing from the living God.

Heb. 4: 1Let us therefore fear, lest, a promise being left us of entering into his
rest, any of you should seem to come short of it.

Heb. 4: 11 Let
us labor therefore to enter into that rest, lest any man
fall after the same example of unbelief.

Heb. 12: 15
Looking diligently lest any man fail of the grace of God; lest any root of
bitterness springing up trouble you, and thereby many be defiled;
